`llo all whom it may concern:

Be it known that we, JOHN BARBERIE and Ti-IoMAs J. WALSH, citizens of the United States of America, and residing at Brooklyn, inthe county of Kings and State of New Yorlg have invented certain new and useful Improvements in Safety Apparatusfor Mo- `tor-Cars, of which the following is a specification, such as will enable thoseskilled in the artto which it appertains to make and use .the same.

The object of this invention is to provide a safety apparatus for motor cars whereby, if asignal be set and the motorman fails to see the same, the electric power of said car ymay be automatically shut H, the brakes setand the car `brought to a stand still a I further object of this invention being to provide such an apparatus whereby the motorman, if he so desires, may pass the set signal but in so d oing must cut oif the motive power of said car while passing the signal and a still further object being to provide an apparatus of this class which is simple and effective in operation and construction and comparatively inexpensive.

Our invention is fully described in the following specification of which the accompaof cautionary signal and home or main signal.

Inthe drawings forming part of this speciv cation, we have shown a portion of the interror of a motor car a, mounted on wheels e2, only one of which is shown, and said wheel-moving on a traclr or rail a3 and the 4caral is provided with the usual controller boX l) provided with a handle b2 and, in practice, the handle `b2 is mounted upon a casing `c within which is pivoteda plate c2 of the same size as the inner surfaces of said "casing and free to move therem upon its pivot c3 and the controller handle is secured to the pivote3 and therefore moves with the l plate` c2 and connected with one end of the casing c and adjacent to the normal position of the plate c2 is a pipe 04 connected with the l main reservoir of the compressed air supply as shown at c5 and the pipe cLL is provided with a valve c normally closed and said valve is provided with a stem c7.

As shown in Fig. l, the valve stem c7 is in o erative connection with a motor d and a so in connection with said motor is a stem d2 of a valve d3 mounted in a pipe d4, said pipe being the train line pipe ofthe air brake system and the valve d is also normally closed and, as will be seen, when the motor d is energized, the valves cG and d3 are opened, the stems thereof being provided with stops or other suitable devices for limiting the operation of the motor d to 90 degrees, and the compressed air from the reservoir c5 passes to the casing c and the plate c2 is forced outwardly as well as the controller handle t2 and the motive power to the main motor e is therefore shut off and at the same time the air in the train line pi e d4 is permitted to escape and the bra res are set thereby.

At e2 we have indicated the usual third-rail of an electric railway system and with which a shoe e3 is adapted to operate, said shoe being in electrical connection with the motor e by means of a wire e4 and connected with the other side of said motor e, and with a switch e5 is a wire e7 and the eXtreme outer contact of a rheostat e8 upon which the switch c5 operates, is connected with the controller box b by means of a wire c and the other side of said controller is connected with the ground rail a3 by means of a wire f 2 and it will therefore be seen that when the rail e2 is energized, the current passes through the motor e, switch e5, controller t and ground rail a3 and is controlled by means of the handle b2 in the usual manner.

Adjacent to the third-rail e2, and parallel thereto is a rail nwhich is not continuons but of a length great enough to suit the requirements of the road upon which our apparatus is used and passing therethrough is a slide bar h2 operated by means of a semaphore or other signal h3 to slide toward the thirdrail e2 when the said signal is set at the danger point and the slide bar h2 is composed of conductive material and, when in contact with the third-rail c2 said supplemental rail 7i is in electrical communication with said third rail and ready to be energized when a circuit is completed therethrough or if the said rail 71, be grounded and mounted upon the caro 1s a supplemental shoe h4 adapted to slide upon the rail h, as clearly shown in Fig. 1.

At any convenient place on the car a is a sup lemental motor d already described and saidp motor d is connected with the supplemental shoe h4 by a wire h5 and connected with the other side of said motor d is a Wire he the other end of which is connected with a contact k7 adjacent to the switch e5 and carried by said switch but insulated therefrom is a plate hs which is normally in connection with the contact k7 and a wire 7L connects said plate hs with the wire f2 or grounded in any other suitable manner. It will therefore be seen that when the third rail e2 is energized, the motor e is operated and the car moves, but only when the switch e5 is in its normal position as shown in full lines and when the slide bar h2 is out of contact with the third-rail e2 and if the signal h3 be set at the danger point the slide-bar is forced toward the third-rail e2 and touches the same and the current passes through the shoe h4, Wire h5, motor d, wire h6, contact k7, plate hs, wire h, wiref2 and return rail a3 and the motor d is actuated and the valves cG and d3 are operated into the positions shown in the drawing and the compressed air from the reservoir c5, as previously described, shuts oif the motive power and the brakes of the car are set by the air escaping from the pipe d4 and the car is brought to a standstill. If, however, the motorman for any reason desires to pass the signal while he is under Way, he operates the switch e5 to the position indi cated in dotted lines in Fig. l, at which time he breaks the connection between the plate hs and contact k7, but at the same time cuts out the main circuit and thereby reduces the speed of the motor e and the car gradually stops, the brakes not having been set by this operation and, upon returning the switch e5 to its normal position, the main circuit is again completed and if he has at this time passed the section or block of the supplemental rail h, 0r if the signal be returned to the safety position, the motor d is denergized and the valves c and d3 may be returned to their normal positions by means of a handle 'i which has been forced against the stop i2 by the operation of the motor d and the apparatus is ready for use with another rail ZL and signal h3.

In practice, we prefer to connect our track apparatus with the usual or any desired cautionary signal placed at some distance from the home or main signal, the object being that, if the inotorman fails to see the cautionary signal when set at danger, the car is stopped automatically and warns him t0 proceed with care, for, if no cautionary signal were employed and he passed the home signal without seeing the same, the impetus of the car would carry it for some distance beyond the signal and perhaps result in accident.

` Although We have Vshown our apparatus connected with the third-rail system, it will be obvious that the same may be easily adapted for Ythe trolley system and we prefer to so arrange our apparatus that, where motor cars change from one system to the other as is frequently done, the result desired Will be accomplished with either system, it being necessary, however, to employ the track ap'- paratus shown or otherY similar devices, and various other changes in and modifications of the construction herein shown and described may be made without departing from the spirit of ourinvention or sacrificing its advantages, and with this reservation,
